It would be infuriating if this doesn't come with ECC RAM support.

It's infuriating ECC RAM doesn't come in everything.

  ECC RAM is stuck at 2666 MT/s and rarely overclocks to 1.35V. Normal RAM can handle 1.35V typically and often goes up to 3200 MT/s (on AMD systems) or 3600 MT/s (on Intel systems). That's easily +20% to +35% more memory bandwidth. With lower latency and better overall specs to boot. And if your 3d render has a pixel-error on frame 50, delete the .png file and rerender frame 50. No biggie.

    That sounds like an artifact of Intel's artificial market segmentation. If we imagine a world where ECC was mandatory then it's likely that ECC gamer RAM would be available.

    Well, I obviously didn't mean hardware meant for specific applications where ECC would do notably more harm than good must use ECC anyway nor that non-ECC memory should not be available to those who consciously want it. Perhaps graphics rendering farms should be built with non-ECC RAM or with both kinds used together (ECC for the system code and non-ECC for the graphical data). As for me I'm just annoyed by the fact I have never seen a laptop that supports ECC (as for now it seems there actually are a couple of models e.g. ThinkPad P70). I personally don't really care about the RAM bandwidth, I'm still using DDR2 anyway, but I would love to use ECC.

I wonder if there isn't some way to manufacture ECC RAM that doesn't need CPU support? It could act towards the CPU/motherboard as if it's non-ECC RAM but still contain 9 bits per byte inside. The RAM chip itself would do any computation if needed instead of the CPU, and if it needs to give interrupts to warn about error conditions, it could output it as an electric signal you can hook up to anything you want yourself (including to the CPU in some way, like via USB or something lower level, or otherwise a warning light or beep or so)

  For a read, the CPU receives the data. The CPU memory controller needs to check ECC. There's no way around this.
